Abstract - performance for the benefit of users and the city. With the growth of cities, the need for people for transport increases, and not all of these journeys may be in private transport due to congestion that is generated. Therefore, the government must provide a transit system well distributed and organized to meet the demand efficiently. All this must be planned with a holistic view of the problem in order to get the best use of economic resources, the best functionality for commuters, preserve the environment and make energy savings Optimization has importance in different aspects, it may be in cost, distance, time, aspects.The objective of the mini project is to check bus routes (within Thrissur district) of Jyothi Engineering College are efficient in all aspects with the help of Arc-GIS. Network analysis is the basic operation involved in this work. Creating a georeferenced base map of
Thrissur, and digitized bus routes are the basic requirements. Attribute data includes the demand from each stop (impedance), speed, distance etc. For network analysis, “network analyst” tool in Arc tool box is used. After
Geo referencing and Digitization attribute values assigned to the each routes with the help of proximity tools and then run the analysis will give the shortest path. If the shortest path obtained is same as current route then the route is efficient .

Transportation is the movement of humans, animals and goods from one location to another. In the 21st century there is huge importance given to management, logistics and networking and this is mainly done so that the overall efficiency of each sector gets improved.In this particular project, the importance is mainly given onto the transit networking problem, i.e. bus route problem where busses will carry people from one location to another along different routes with intermediate stops. Problem is considered to be complex in nature due to the multiple variables and parameters. Considering the two depots
(end points) there will be many route combinations possible. Those alternate routes may have different characteristics like distance, cost, time etc.
The advancement in route optimization where a solution loads and distributes routes and stops based on achieving the minimum miles driven can drastically reduce fuel use, vehicle wear and tear and exposure risk, which has an impact on violations, accidents, and insurance premiums.
Another importance of this problem is the shortest path finding out, which is very important in the 21st century world is because at present time is money and we humans are trying to cut short on everything. So as the networking and linking sector among all other sectors and hence it is important that we find ways and methods to improve the efficiency of the same.

3. 0 DATA COLLECTION AND METHODOLOGY
Study Area
Efficient transportation and transportation scheduling is a huge challenge due to the various constraints of time distance and cost. Therefore it is very important to find out ways of optimizing and if possible suggesting a more suitable route which is optimized in both cost and time which can be used for a variety of cases which thus shall make it very flexible in nature. So project will be focusing on the bus network of the Jyothi Engineering College. There are 18 college buses running to different directions in
Thrissur district. The prime objective of the work is to identify the shortest path from the college to various destinations.
Specific objectives of the projects are, i. Studying the basics of Arc-GIS software and the route optimization techniques used in Arc-GIS ii. Checking the efficiency of the current routes with the help of Arc-GIS network analyst.
Methodology Adopted i. Collection of base map and bus data ii. Importing Base map to Arc-GIS
III. Geo referencing of base map iv. Digitization of road network Iv. Database creation v. Analysis using network analyst tool
Data required for the present study are base map of study area that includes the different places in Thrissur district. A base map of Thrissur district is needed or we can use the online Arc map for that purpose. Bus data includes the cost, distance, time as additional attributes.Georeferencing is the process of assigning spatial coordinates to data. When co- ordinates of spatial dates are referenced to their corresponding positions on the surface of earth then it is called Georeferencing of spatial data.Digitizing is a process of encoding geographic features in digital form as x, y coordinates. It is carried out in order to create spatial data from existing hardcopy maps and documents. There are three types of features used for digitization purpose, point, line and polygon features. Bus stations, railway stations, hospitals, places of tourist interest, offices, educational institutions and stadiums and various facilities in the study area are digitized as point features,lakes and rivers are digitized as polygon features, . Roads, streets and railway lines are digitized as line features.
Steps for Georeferencing
The base map is dead without adding the real earth coordinates into it. For the analysis the map without real features wont work. Scanned maps don’t usually contain information as to where the area represented on the map fits on the surface of the earth. The location information delivered with aerial photos and satellite imaginary is often inadequate to perform analysis or display in proper alignment with other data.Very essential information may be contained in data or images that were produced at a different point of time. It may be desired either to combine or compare this data with that currently available. The latter can be used to analyze the changes in the features under study over a period of time.Georeferencing is crucial to making aerial and satellite imagery, usually raster images, useful for mapping as it explains how other data, such as the above GPS points, relate to the imagery.
Different maps may use different projection systems.
Georeferencing tools contain methods to combine and overlay these maps with minimum distortion. Steps for the georeferencing is given below.
1. Start ArcMap.
2. Add base map click “add data”.
3. Add the geographical map that is to be aligned with the base map.
4. Select four control points, in such a way that that four points should be uniformly distributed throughout the base map.
5. The latitude and longitude of corresponding control points were added.
6. Click “Go to XY”With that of the geographical map.
7. Save the geo-referencing information.
The following dialogue box will appear while entering the latitude and longitude of each control points.

Steps for digitization
Digitization can be done by two methods, Manual digitization and heads up digitization. In this method, the digitizer uses a digitizing tablet (also known as a digitizer, graphics tablet, or touch tablet) to trace the points, lines and polygons of a hard-copy map. This is done using a special magnetic pen, or stylus, that feeds information into a computer to create an identical, digital map. Manual
Digitizing is still a useful technique because of its ability to accurately copy maps in poor condition. Computers have a higher risk of error when interpreting information contained on a faded, stained, or poor quality map or image. Heads up digitization involves scanning a map or image into a computer. The digitizer then traces the points, lines and polygons using digitizing software. This method of digitizing has been named "heads- up" digitizing because the focus of the user is up on the screen, rather than down on a digitizing tablet. It has largely replaced manual digitizing because of its speed and accuracy. It is, however, limited to using scans of high quality maps and images. i.

Database creation
Database creation is one of the most important part in the analysis. Marked the major junctions,distance to reach each junction from the origin, etc. This is done by adding required number of fields and entering the data for all the features in their corresponding records.Recently there are
18 college buses within the Thrissur district and 3 of them are towards the Palakkad direction.Created 4 layers, such as landmark, road, road junctions, bus stops for the easiness in the database creation. Input data includes the speed in different roads ( for National Highway it is given
80Kmph and for State Highway it is given 60Kmph), demand of students from each stops for the whole route.
For adding attribute data to these 4 layers created new feature class. The feature class window is given below in

From the feature class select the appropriate one to create the landmark layer. Then each of the point features were named as stops. By selecting the each point layer it’s possible to add the attributes that need to be considered in the analysis. Here the attributes considered are cost, distance and time. The attribute table made for the analysis is given below in the figure 5. While digitization the software itself will calculate the shape length between the features that created for the analysis. There is a possibility of putting impedance / barriers / or the real earth feature in between the stops. But for wide range of survey and observations are needed. map. For that the following steps should be followed. (Fig.7 and Fig.8)

4. ROUTE OPTIMIZATION USING NETWORK ANALYST
Route optimization is done by the Arc-GIS tool named network analyst. The Network Analyst toolbox contains tools that perform network analysis and network dataset maintenance. This toolbox, can maintain network datasets that model transportation networks and perform route, closest facility, service area, origin-destination cost matrix, vehicle routing problem, and location-allocation network analyses on transportation networks. The tool box is shown below in Fig.6
Fig.8 Create Network Location Tool
After selecting the create network location tool ,choose the two places (origin and destination) that is to be optimized(mostly the shortest path between the origin and destination.). The given below figure 9. shows the result when the origin is college and destination is kodakara.
(Blue line indicates the shortest path).
Fig.6 Network Analyst Tool
The above mentioned tool can also selected from the Arctoolbox also. There are different college buses running to different directions of Thrissur. For finding out the optimized routes need to select two points in the digitized

5.0 RESULT AND CONCLUSIONS
All the bus routes were analyzed with the above given procedure by assigning the attributes distance, time, demand from each stops (considered as impedance) and with the help of network analyst, it’s found that the existing bus routes are optimum based on the travel time and distance aspect. To achieve an optimized route in distance and time aspect, need to analyses the each bus routes separately with the help of “Vehicle routing problem “in the network analyst tool. Alternate routes can be suggested but the demand from those sides are less. So it will not be profitable decision, hence difficult to implement.
